Please read this important study on post-tx experiences***

Sandalwood posted this study in the thread below on long term side effects after tx.  I found this to be a real eye opener, in that it really validates the randon percentages of treaters that are reporting the exact same problems we have been discussing here on the forum.  Thanks for posting this study, because it is very personal, comprehensive, and jarring!  Look at the percentages of the 27 test subjects who report all sorts of issues.  Consider how this random group could be extrapolated out into the entire treating community.  I find the comments and conclusions in this piece to be the FIRST and ONLY that have honestly and thoroughly looked at this issue.  The actual experiences of people after finishing therapy.  For those that scoff at the idea of therapy after effects, or think its only a small, insignificant group....READ THIS STUDY.  

Thanks for finding this study Sandalwood.!!!  Its unique.  Here is the link.  Note especially pages 16-20...and conclusions...


I think we have only scratched the surface of the iceberg here on the forum.  Who knows what the real long term issues might really involve, and how many are really affected.  Like people say in the study...Where ARE the studies?  Who did warn any of us of these long term problems?  What are the doctors and drug companies doing to find out what is really the status?   Read and enjoy....or cry...whatever the case.

I agree completely!  They do drop you like a hot potato and usually dismiss any conversation about ongoing side effects....which we all know by now are very possible...and can be permanent.  Very little is ever even mentioned about the potential for long term problems when going into and through tx.  I do, by the way, have a great GP, who is also very aware of Interferon related issues, and treats a group of people who have long term side effects.  We have not yet found any real answers yet, though.  Its unfortunate, but I think in the case of permanent side effects, or prolonged side effects, there seems to be no ideas around what might help reduce or mitigate them.  It was noted that only a few people in the study DID NOT have side effects after stopping tx...and six had long term, and ongoing side effects...all similar in pattern.  (close to a quarter of the group!!)

Now, people may protest about the small group, and how can it be valid, and on and on, always trying to delegitimize any and all claims that this is a frequent occurrence. Well I would just like to see one study presented that presents a DIFFERENT picture.  Its always 'the group is too small', or its not selected properly, or they were people with problems looking for an outlet, etc.  The only thing they do not do is show us an empirical study showing that it is indeed only a miniscule percentage who have these long term problems.  I am sorry, I have not been able to find ANY of these studies.  Of course, the nay-sayers always ASSUME that the vast majority of treaters make out very well after tx, using their own very subjective and opinionated approach to make their point.  I see no evidence or scientific support for any of THEIR claims, nor do I see those thousands of people posting on forums of how fantastic they feel now, after finishing therapy.  Oh, I know the answer already.....they have ALL run away, so happy with life they never go on a forum again....just too perked up and energized to pay any attention to any of that old HCV and treatment related stuff!!!  Right?  The scientific approach to the question once again. All assumptions...on their part.  Really.

The point I make, is that multiple studies NEED to be done on a very large scale, and  looked at closely by the medical and pharmaceutical community.  We need answers, not glib replies, and dismissive attitudes.  This issue was discussed several times in the linked article.  People all over the world apparently are having similar reactions to what they were 'told' going into tx.  I don't think its just a bunch of us on this particular forum.  The lack of medical oversight and responsibility relating to this issue is truly appalling!

I would consider the neurologist who is treating my peripheral neuropathy to be extremely competent. When he learned I had been on IFN tx, the first thing he asked was when the neuropathy manifested after my tx. Based on that, he feels the neuropathy was a result of my diabetes rather than IFN. I have another appt. in a couple months - I'll try to remember to ask him what expeience he has with this issue and/or what he based his opinion on. Apparently there are specialists who are dealing with these issues or there is some type of info out there on which he based his opinion.

I don't believe one can prove a negative.  It's up to the positive to be proven.  :)

You may also have read that diabetes can be exacerbated by the tx, along with many cases of peripheral neuropathy that have developed after ending tx, with or without diabetes as a causitive or complicating factor.
I think there have been quite a few posters on the forum who have complained of developing PN after doing tx.  I would explore this potential issue as thoroughly as possible to determine how many cases are being reported as a result of Interferon treatment.  I am not confident that a neurologist would have that information at hand unless they also treat a good sized cross section of people having been on Interferon in the past.  I am also pretty sure they have very little clue as to what is going on with Interferon post-tx problems, since there has been little publicity on this subject in the medical journals...as we are all painfully aware...   Good luck.

I guess you are going believe whatever you want to believe, which is fine. But presenting your conjecture as fact with no basis is not productive.
GPs have no extensive knowledge about hepatitis C, liver disease or drugs. So while they may be likeable people doesn't make then an expert by any stretch of the imagination. Because some people are not warned of the possible complications of interferon can't be generalized to every doctor. For example I was specifically warned that treatment could cause my liver to fail. In order to prepare for such a situation a was first put on a transplant list in case the small case of liver failure happened. One on the first things the old-timers on this forum recommend to anyone is to find a knowledgeable and experienced specialist.

"They do drop you like a hot potato and usually dismiss any conversation about ongoing side effects..." Sorry, but you have had bad doctors.

"only a few people in the study DID NOT have side effects after stopping tx..."
Total nonsense.

"Well I would just like to see one study presented that presents a DIFFERENT picture."
"I have not been able to find ANY of these studies."
All studies regarding the treatment of HCV do. That you won't or can't read them doesn't change the facts.

"The point I make, is that multiple studies NEED to be done on a very large scale, and  looked at closely by the medical and pharmaceutical community. "
Studies to prove or disprove what?

" I am also pretty sure they have very little clue as to what is going on with Interferon post-tx problems, since there has been little publicity on this subject in the medical journals...as we are all painfully aware... "
What medical journals do you read? Medical journals have no studies or articles regarding side effects of peg-interferon? Surely you are joking?

I will post some of the non-warnings of peg-interferon that you say is so unknown to the medical community and patients. It is part of the "top secret" Pegasys label.

446474 tn?1446347682
Here are some of the warnings that you say doesn't exist and it not acknowledged regarding peg-interferon. I can't even fit all the warning text into a post. Just because you are not aware of the warnings that come with the drug doesn't mean everyone is an unaware as yourself.
I don't know how clearer the warnings can be.
(peginterferon alfa-2a)
28 General

129 Patients should be monitored for the following serious conditions, some of
130 which may become life threatening. Patients with persistently severe or
131 worsening signs or symptoms should have their therapy withdrawn (see

133 Neuropsychiatric
134 Life-threatening neuropsychiatric reactions may manifest in patients receiving
135 therapy with PEGASYS. Depression, suicidal ideation, and suicidal attempt
136 may occur in patients with and without previous psychiatric illness.
137 PEGASYS should be used with extreme caution in patients who report a
138 history of depression. Neuropsychiatric adverse events observed with alpha
139 interferon treatment include relapse of drug addiction, drug overdose,
140 aggressive behavior, psychoses, hallucinations, bipolar disorders and mania.
141 Physicians should monitor all patients for evidence of depression and other
142 psychiatric symptoms. Patients should be advised to report any sign or
143 symptom of depression or suicidal ideation to their prescribing physicians. In
144 severe cases, therapy should be stopped immediately and psychiatric
145 intervention instituted (see ADVERSE REACTIONS and DOSAGE AND

147 Bone Marrow Toxicity
148 PEGASYS suppresses bone marrow function and may result in severe
149 cytopenias. Very rarely alpha interferons may be associated with aplastic
150 anemia. It is advised that complete blood counts (CBC) be obtained pre151
treatment and monitored routinely during therapy (see PRECAUTIONS:
152 Laboratory Tests).
153 PEGASYS should be used with caution in patients with baseline neutrophil
154 counts <1500 cells/mm3, with baseline platelet counts <90,000 cells/mm3 or
155 baseline hemoglobin <10 g/dL. PEGASYS therapy should be discontinued, at
156 least temporarily, in patients who develop severe decreases in neutrophil
157 and/or platelet counts (see DOSAGE AND ADMINISTRATION: Dose
158 Modifications ).

159 Cardiovascular Disorders
160 Hypertension, supraventricular arrhythmias, chest pain, and myocardial
161 infarction have been observed in patients treated with PEGASYS.
162 PEGASYS should be administered with caution to patients with preexisting
163 cardiac disease.
164 Hypersensitivity
165 Severe acute hypersensitivity reactions (eg, urticaria, angioedema,
166 bronchoconstriction, anaphylaxis) have been rarely observed during alpha
167 interferon therapy. If such reaction occurs, therapy with PEGASYS should be
168 discontinued and appropriate medical therapy immediately instituted.
169 Endocrine Disorders

170 PEGASYS causes or aggravates hypothyroidism and hyperthyroidism.
171 Hyperglycemia, hypoglycemia, and diabetes mellitus have been observed to
172 develop in patients treated with PEGASYS. Patients with these conditions at
173 baseline who cannot be effectively treated by medication should not begin
174 PEGASYS therapy. Patients who develop these conditions during treatment
175 and cannot be controlled with medication may require discontinuation of
176 PEGASYS therapy.

177 Autoimmune Disorders
178 Development or exacerbation of autoimmune disorders including myositis,
179 hepatitis ITP, psoriasis, rheumatoid arthritis, interstitial nephritis, thyroiditis,
180 and systemic lupus erythematosus have been reported in patients receiving
181 alpha interferon. PEGASYS should be used with caution in patients with
182 autoimmune disorders.
183 Pulmonary Disorders
184 Dyspnea, pulmonary infiltrates, pneumonia, bronchiolitis obliterans,
185 interstitial pneumonitis and sarcoidosis, some resulting in respiratory failure
186 and/or patient deaths, may be induced or aggravated by PEGASYS or alpha
187 interferon therapy. Patients who develop persistent or unexplained pulmonary
188 infiltrates or pulmonary function impairment should discontinue treatment
189 with PEGASYS.

190 Colitis
191 Hemorrhagic/ischemic colitis, sometimes fatal, has been observed within 12
192 weeks of starting alpha interferon treatment. Abdominal pain, bloody diarrhea,
193 and fever are the typical manifestations of colitis. PEGASYS should be
194 discontinued immediately if these symptoms develop. The colitis usually
195 resolves within 1 to 3 weeks of discontinuation of alpha interferon.

196 colitis has also been observed in patients treated with alpha interferon.
197 Pancreatitis
198 Pancreatitis, sometimes fatal, has occurred during alpha interferon treatment.
199 PEGASYS should be suspended if symptoms or signs suggestive of
200 pancreatitis are observed. PEGASYS should be discontinued in patients
201 diagnosed with pancreatitis.

202 Ophthalmologic Disorders
203 Decrease or loss of vision, retinopathy including macular edema, retinal artery
204 or vein thrombosis, retinal hemorrhages and cotton wool spots, optic neuritis,
205 and papilledema are induced or aggravated by treatment with PEGASYS or
206 other alpha interferons. All patients should receive an eye examination at
207 baseline. Patients with preexisting ophthalmologic disorders (eg, diabetic or
208 hypertensive retinopathy) should receive periodic ophthalmologic exams
209 during interferon alpha treatment. Any patient who develops ocular symptoms
210 should receive a prompt and complete eye examination. PEGASYS treatment
211 should be discontinued in patients who develop new or worsening
212 ophthalmologic disorders.
214 General
215 ·  The safety and efficacy of PEGASYS have not been established in
216 patients who have failed other alpha interferon treatments.
217 ·  The safety and efficacy of PEGASYS for the treatment of hepatitis C in
218 liver or other organ transplant recipients have not been established.
219 ·  The safety and efficacy of PEGASYS for the treatment of patients with
220 HCV co- infected with human immunodeficiency virus (HIV) or hepatitis
221 B virus (HBV) have not been established.
222 Renal Impairment
223 A 25% to 45% higher exposure to PEGASYS is seen in subjects undergoing
224 hemodialysis. In patients with impaired renal function, signs and symptoms of
225 interferon toxicity should be closely monitored. Doses of PEGASYS should
226 be adjusted accordingly. PEGASYS should be used with caution in patients
227 with creatinine clearance <50 mL/min (see DOSAGE AND
228 ADMINISTRATION: Dose Modifications ).
229 Information for Patients
230 Patients receiving PEGASYS should be directed in its appropriate use,
231 informed of the benefits and risks associated with treatment, and referred to
232 the PEGASYS Medication Guide.
